When cultivating kangusa, which is used to make tatami mats, rice fields are usually used after the rice has been harvested, but kangusa does not grow well if left in paddy fields, so it is necessary to dry the field. However, the cultivation period for Guancao is limited until the next rice cultivation, and the time period for cultivating and leveling the land as a Guancao field is only 2 to 3 months, so it is required to dry the field as quickly as possible. Currently, trenches are created by digging along the edges of the ridges around the field with plows, shovels, etc., and the excavated soil is piled up on the sides of the trench, but this results in poor drainage of the field and also reduces the need for later plowing work. Because this poses a problem, the soil must be crushed and dispersed into unused areas of the field.
This work, along with trench digging, requires a great deal of time and effort, and improvements have been desired.

Therefore, the purpose of the present invention is to solve the above-mentioned problems by instantly scattering the soil in the dug trench far away, without creating a pile of soil that impedes drainage, and by making the shape of the dug trench square. To provide a trench digging machine that efficiently excavates a square trench with a rough shape.

Next, the operating conditions and effects of the trench excavator of the present invention will be explained. 4 to 8 are diagrams showing the operating status of the trench excavator. FIG. 4 is a diagram explaining the positional relationship of the three tilling claws, and since the rotating shaft 6 of the present invention is gradually inclined downward toward the rear,
The tilling claws 12a, 12b, and 12c are located sequentially downward. Therefore, the tilling claw 12a at the forefront digs shallowly into the unexcavated ground, and the next tilling claw 12b
will dig a deeper groove than this, and the claw 12c at the rear will dig the deepest. Since the rotating shaft 6 is tilted downward and the heights of the tilling claws are different in this way, the digging resistance of each tilling claw can be equalized. Furthermore, as will be described later, the tilling claws scatter the excavated soil, and the amount of soil at this time is approximately equal for each claw, which has the effect of making the scattering even.

On the other hand, the cutting blade 17 is an L-shaped plate having a part perpendicular to the ground and a part horizontal, and the position of the horizontal part is equal to the lowest end of the tilling claw 12c. And, the vertical part and the horizontal part are respectively tilling claws 12c.
The tip of the circle almost coincides with the tangent to the circle drawn by rotation. Therefore, soil having a triangular cross section is released between the L-shaped corner of the cutting blade 17 and the circle drawn by the rotation of the tip of the tilling claw 12c. FIG. 5 is a plan view showing how the rotary shaft is being rotated to dig a trench, FIG. 6 is a sectional view thereof, and FIG. 7 is a sectional view showing how soil is being scattered. As is clear from Figure 5, the width of the trench to be excavated is 12 plowing claws.
It differs depending on a, 12b, and 12c. Further, the cutting blade 17 is provided between the tilling claws 12b and 12c. This is at least tilling claw 12c
It is necessary to be located in front of the
Preferably, it is located just in front of the rearmost pawl 12c. By doing so, the amount of soil cut by the cutting blade 17 is reduced, and cutting resistance can be reduced. As shown in FIG. 6, the corner soil 22 released by the cutting blade 17 is accompanied by the scraping operation of the rearmost tilling claw 12c and is spread out of the groove. Further, in this embodiment, a disk-shaped cutter 19 that freely rotates in front of the cutting blade 17 is provided to cut into the unexcavated ground, so that the cutting resistance of the cutting blade 17 is advantageously reduced. Figure 7 shows the situation in which the excavated soil is spread over a long distance, and the tilling claws 12 have blades bent in a spiral shape and rotate at high speed, so the excavated soil is spread instantly. are scattered onto uncultivated land and are not piled up near ditches.
FIG. 8 is a perspective view of the trench-digging machine during trench-digging work, and a square, orderly trench is formed on the ridge side. In the above embodiment, one cutting blade 17 is installed on the ridge side, but by installing this on both sides, a perfectly square groove can be dug.
